Description
One, technical field
The utility model relates to a kind of connecting terminal apparatus, especially a kind of connecting terminal apparatus for transformer.
Two, background technology
In large-scale power transformer manufactures, general use binding post is as the carrier of big current, therefore the connecting terminal apparatus for transformer is a kind of important transformer part, existing in the connecting terminal apparatus of transformer, more common syndeton is at the copper rod needing to connect or binding post two sides corresponding tapping and brill counterbore respectively, hexangular cylindrical screw fastening in adopting, because steel screw thread is different with intensity with the hardness of copper screw thread, easily come off copper scale, simultaneously owing to using screw to link with one of them copper rod or binding post but linking intensity is low.
Three, summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of connecting terminal apparatus for transformer, therefore ensure that the same intensity of link, improves bonding strength.
For achieving the above object, the technical scheme that the utility model is taked is: include and to connect with wire and to have the binding post I of fixing hole and binding post II, be arranged through the fixing hole of binding post I and binding post II and the screw bolt and nut that binding post I and binding post II are fixedly connected, be set to the aluminium foil that covers on screw bolt and nut, nut is set to connect with bolt thread formula.
Owing to devising binding post I, bolt, nut, aluminium foil and binding post II, by screw bolt and nut, binding post I and binding post II are linked together, the lashing force produced by screw bolt and nut achieves a butt joint the connection of line terminals I and binding post II, no longer achieved a butt joint by the lashing force of bolt and binding post I or binding post II connection of line terminals I and binding post II, therefore ensure that the same intensity of link, improve bonding strength.
The utility model devises, binding post I is arranged on binding post II plane formula contact connection and bolt is arranged through binding post I and binding post II, nut is set to Bolt Connection and is set to and passes binding post I or binding post II, and the edge part that aluminium foil is set to cover also aluminium foil on screw bolt and nut is set to be embedded in screw bolt and nut and the gap between binding post I and binding post II.
The utility model devises, and binding post I and binding post II are respectively arranged with the step surface in centrally face and the lateral surface of the assembly of binding post I and binding post II is set to extend along the lateral surface continous way of binding post I and binding post II.
The utility model devises, and the lateral surface of binding post I with binding post II is respectively arranged with the groove corresponding with the end of bolt and nut.
In the technical program, the screw bolt and nut producing the end face lashing force of the connection of pair of wire connection terminals I and binding post II is important technical characteristic, in the technical field of the connecting terminal apparatus for transformer, has novelty, creativeness and practicality.
Four, accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Five, embodiment
Fig. 1 is an embodiment of the present utility model, illustrate the present embodiment by reference to the accompanying drawings, include binding post I 1, bolt 2, nut 3, aluminium foil 4 and binding post II 5, binding post I 1 is arranged on binding post II 5 plane formula contact connection and bolt 2 is arranged through binding post I 1 and binding post II 5, nut 3 is set to connect with bolt 2 and is set to and passes binding post I 1 or binding post II 5, aluminium foil 4 is set to cover on bolt 2 and nut 3 and the edge part of aluminium foil 4 is set to be embedded in bolt 2 and nut 3 and the gap between binding post I 1 and binding post II 5.
In the present embodiment, binding post I 1 and binding post II 5 are respectively arranged with the step surface in centrally face and the lateral surface of the assembly of binding post I 1 and binding post II 5 is set to extend along the lateral surface continous way of binding post I 1 and binding post II 5.
In the present embodiment, the lateral surface of binding post I 1 and binding post II 5 is respectively arranged with the groove corresponding with the end of bolt 2 and nut 3.
By bolt 2 and nut 3, binding post I 1 and binding post II 5 are linked together, the end of bolt 2 and nut 3 is made to be placed in the groove of binding post I 1 and binding post II 5, when bolt 2 and nut 3 link together binding post I 1 and binding post II 5, binding post I 1 and binding post II 5 realize seamless connection, bolt 2 and nut 3 and do not protrude on the lateral surface of binding post I 1 and binding post II 5.
The utility model has lower feature:
1, owing to devising binding post I 1, bolt 2, nut 3, aluminium foil 4 and binding post II 5, by bolt 2 and nut 3, binding post I 1 and binding post II 5 are linked together, the lashing force produced by bolt 2 and nut 3 achieves a butt joint the connection of line terminals I 1 and binding post II 5, no longer achieved a butt joint by the lashing force of bolt 2 and binding post I 1 or binding post II 5 connection of line terminals I 1 and binding post II 5, therefore ensure that the same intensity of link, improve bonding strength.
2, owing to devising bolt 2 and nut 3, achieve the connection of end face pair of wire connection terminals I 1 and binding post II 5, no longer realize side connected mode, improve bonding strength.
3, owing to devising bolt 2 and nut 3, make bolt 2 no longer carry out side cutting with binding post I 1 or binding post II 5, do not produce and chip, improve security performance.
4, connecting hole is all designed to counterbore but not counterbore and the setting of silk span, reduces difficulty of processing; Employing Steel Bolt is connected with nut but not Steel Bolt is threaded with copper, improves bonding strength; Blackout Steel Bolt can not come off when being connected with nut copper scale, improves the electric property of lead-in wire connection.
The technical characteristic connected with that produce pair of wire connection terminals I 1 and binding post II 5 bolt 2 of end face lashing force of connection and nut 3 that is that also have other is all one of embodiment of the present utility model, therefore in the connecting terminal apparatus technical field of transformer, every including to connect with wire and to have binding post I 1 and the binding post II 5 of fixing hole, be arranged through the fixing hole of binding post I 1 and binding post II 5 and the bolt 2 that binding post I 1 and binding post II 5 are fixedly connected and nut 3, be set to cover the aluminium foil 4 on bolt 2 and nut 3, the technology contents that nut 3 is set to connect with bolt 2 screw-type is all in protection range of the present utility model.
